Articolul prezintă un studiu de caz privind proprietăţile antimicrobiene ale pulberilor de fructe de pădure asupra microorganismelor patogene, care pot coloniza în mod accidental produsele din carne. Au fost testate proprietăţile inhibitoare ale pulberilor de măceșe și păducel asupra proliferării microorganismelor patogene și potenţial patogene S. aureus ATCC 25923, Salmonella Abony ATCC 6017, Klebsiella pneumoniae ATCC 13883 și E. coli ATCC 25922. S-a constatat, că includerea pudrei de măceș și de păducel în reţeta de crenvuști a redus rata de creștere a microorganismelor pe eșantioane contaminate intenţionat. Prin studierea fazelor Lag și Logaritmică a vitezei de creștere a microbiotei s-a constatat, că păducelul manifestă efect bacteriostatic mai mare asupra tulpinilor S. aureus ATCC 25923 și E. coli ATCC 25922, iar măceșul are efect bacteriostatic important asupra tulpinilor Salmonella Abony ATCC 6017și Klebsiella pneumoniae, ATCC 13883
This article presents a case study of antimicrobial properties of berry powders on pathogenic microorganisms that can accidentally colonize meat and meat products. We tested the inhibiting properties of rose-hip and hawthorn on the growth of pathogenic and opportunistic pathogenic microorganisms S. aureus ATCC 25923, Salmonella Abony ATCC 6017, Klebsiella pneumoniae ATCC 13883 and E. coli ATCC 25922. We found out that introducing rose-hip and hawthorn powder in the sausage recipe decreased the microorganism growth rate on purposely contaminated samples. By studying Lag and Logaritmic phases of strain growth rate we found that hawthorn has a greater bacteriostatic effect on S. aureus ATCC 25923 and E. coli ATCC 25922 strains, and rose-hip has a greater bacteriostatic effect on Salmonella Abony ATCC 6017, Klebsiella pneumoniae ATCC 13883 strains.
